Dimeric and multimeric aggregates of a model metalloporphyrin, zinc tetraphenylporphyrin (ZnTPP), have been produced in a controlled manner by incrementally increasing the water content of dilute aqueous ethanol solutions. Steady state absorption, fl

Multicolor multistep photoisomerization process of azobenzene derivative in photostationary state was observed by newly developed Fourier transform two-dimensional (2D) spectroscopic technique. The photostationary state was generated by excitation us

Spectroscopic, photophysical and computational studies designed to expose and explain the differences in the efficiencies of non-coherent photon upconversion (NCPU) by triplet-triplet annihilation (TTA) have been carried out for a new series of alkyl
*8-amino 2-naphthol (8A2NP) is an interesting molecule containing both proton acceptor (-NH2) and proton donating (-OH) groups. Our earlier investigation on the photophysics / photochemistry of 8A2NP reveals that its prototropic behavior is sensitive

Fluorescence quenching of 8-methyl quinoline in acidified aqueous solution by various halides (Cl −, Br −, I −) is studied using steady state and time resolved fluorescence techniques. The quenching process is characterized by Stern–Volmer (S

Simple composite films consisting of a polymer blended with organic emitters have the potential for broad-band "white" light emission that can be used for general lighting applications. In the present work, a simple mixture of 3-hydroxyisoquinoline (

Controlling aggregation of the dual sensitizer-emitter (S-E) zinc tetraphenylporphyrin (ZnTPP) is an important consideration in solid state noncoherent photon upconversion (NCPU) applications. The Langmuir-Blodgett (LB) technique is a facile means of
