Summary: Room temperature phosphorescence (RTP) in organic aggregates depends on molecular conformation and packing, which pose challenges in understanding the mechanism of polymorphism-dependent RTP. In this study, different RTP lifetimes were observed in organic polymorphs of DOS compounds (DOS-O and DOS-S). By analyzing molecular and electronic structures, and decay dynamics of T(1) states, it was found that the decreased energy gap of T-1 states due to conformational variation is responsible for the shortened RTP lifetime from DOS-O to DOS-S. This was further supported by the good agreement between theory and experiment in RTP lifetime.

Summary: This study reports a facile bottom-up solution fabrication process to obtain metal-free supramolecular glasses (SMGs) at the macroscopic scale using L-Histidine and hexamethylenetetramine as building blocks. The chiral SMGs possess color-tunable ultralong room temperature phosphorescence (decay lifetime up to 141.2 ms) and circular polarized luminescence (g factor up to 8.7x10(-3)). The strong hydrogen bonds effectively drive the formation of SMGs, and provide a rigid microenvironment to boost triplet exciton generation. Applications including multicolored displays, visual UV detection, and persistently luminescent thermometer are demonstrated based on the excitation- and temperature-dependent ultralong phosphorescence of the SMGs.

Summary: This study reports commercially available single-component phosphors based on triphenylmethylamine, which exhibit color-tunable property and ultralong lifetime (0.56 s). Different afterglow colors ranging from cyan to orange were observed under different wavelengths of UV excitation. Crystal structure and calculation studies suggest that multiple emission centers in the aggregated states may be responsible for the color-tunablity. Additionally, visual probing of UV light and colorful anti-counterfeiting were conducted, and the detection of UV light ranging from 350 to 370 nm with a minimal interval of 2 nm was achieved. These findings provide insights into the mechanism and design of single-component color-tunable ultralong organic phosphorescence materials.

Summary: Doping and blending strategies are crucial for controlling excited states and energy levels in conjugated molecular systems. However, effective models and platforms to explore the effects of trapped doped centers on heterogeneous structures and photophysical processes are rarely proposed. In this study, a supramolecular N-B coordination was designed to investigate the impact of molecular doping on film energy levels and photoexcitation dynamics. The results showed that the coordination bond increased N atoms' binding energy and tuned the band-gap, resulting in a new fluorescent emission center with longer excitation and emission wavelengths. The blending films exhibited inconsistent fluorescent behaviors compared to solution due to intermolecular Forster resonance energy transfer. Additionally, the charge transfer state and changed dielectric constant caused a red-shift in the photoluminescence spectra with increased dopant ratio, enabling wide-tunable fluorescent color. The excited state behaviors of the compounds in blending system were further studied using transient absorption spectroscopy. It was found that supramolecular coordination blending effectively improved the photoluminescence quantum yield and conductivity of the films. This exploration in coordination mechanisms provides insights into doped semiconductors and facilitates the development of high-efficient fluorescent systems.

Using multiscale first-principles calculations, this study provides a comprehensive understanding of atomic and charge dynamics in hybrid perovskites. It is revealed that the ultralow room-temperature thermal conductivity and strong anharmonicity are crucial for their decent thermoelectric figure of merit. The study also identifies the role of electrostatic interactions and hydrogen bonding in influencing the coupling motions and charge transport in these materials.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.
