Summary: In this study, a series of trimetallic cyanidometal-bridged compounds were synthesized and characterized. The effect of the potential difference between the central and terminal metals on electron communication was investigated. Experimental results showed the presence of electronic interactions between the terminal Fe atoms, and an increase in the number of methyl substituents weakened the electron communication between the terminal Fe redox centers or between the neighboring Fe and Ru redox centers. All the mixed valence compounds exhibited localized character.

Summary: The impact of EphA2 receptor on cancer malignancy is determined by two different activation methods. PIP2 signaling lipid promotes TM dimerization in a conformation resembling the ligand-independent state, potentially affecting EphA2 activation. The difference in TM crossing angles in the ligand-dependent and ligand-independent states may play a role in regulating EphA2 activity.

Summary: Strong photoinduced oxidants are crucial for organic synthesis and solar energy conversion. A series of DCBT dyes with varying electron donation strengths on the periphery were studied as organic chromophores that can act as strong photooxidants in catalytic systems. The dyes demonstrated long-lived excited states, making them suitable for catalysis, and visible light driven photosensitized water oxidation was successfully achieved using a water-soluble photosensitizer.

Summary: Researchers have observed an unusually strong visible-light absorption band in carbon nitride sheets without introducing a tail-like absorption band. The study reveals a new mechanism involving the extension of a pi-conjugated system and the introduction of cyano groups to expand the absorption band.

Summary: The photophysical properties of monodentate-imine ruthenium complexes do not usually meet the requirements for supramolecular solar energy conversion schemes. Two strategies are explored to extend the excited-state lifetime, which involve chemical modification of the distal N atom of pyrazine. The strategies achieve a 2 orders of magnitude extension of the excited-state lifetime, reaching compatibility with bimolecular or long-range photoinduced reactivity.

Summary: This paper reports two new tris-heteroleptic Ru(II) complexes with triphenylphosphine coordination, which show suitable photochemical properties for photochemotherapeutic applications. The study reveals that under visible light irradiation, the complexes exhibit increased activity due to the photoinduced substitution reaction of PPh3 ligand in the excited state. These complexes represent a new design motif for the selective release of PPh3 and CH3CN for use in photochemotherapy.

Summary: This study investigates the excited states of a series of complexes [Ru(tpy)(L)(CH3CN)]n+ (1-11), and finds that the photoinduced CH3CN dissociation in these complexes occurs from the metal-to-ligand charge transfer (3MLCT) excited state instead of a dissociative triplet ligand field (3LF) state as previously believed. This discovery suggests alternative pathways for ligand photodissociation and has broad implications for the design principles of applications that require ligand photodissociation.
