The anthracene cyclophane bis-anthracene (BA) can undergo a [4 + 4] photocycloaddition reaction that results in a photodimer with two cyclobutane rings. We find that the subsequent dissociation of the dimer, which involves the rupture of two carbon-c

Conjugated polymers blended with graphene represent a possible approach for making organic bulk heterojunction solar cells. In this paper, the time-resolved fluorescence dynamics of poly(3-hexylthiophene-2,5-diyl) (P3HT) and poly[2-methoxy-5-(2′-et

Experimental and theoretical results in support of nonlinear dynamic behavior of photosynthetic reaction centers under light-activated conditions are presented. Different conditions of light adaptation allow for preparation of reaction centers in eit

A model for light-induced charge separation in a donor-acceptor system of the reaction center of photosynthetic bacteria is described. This description is predicated on a self-regulation of the flow of photo-activated electrons due to self-consistent

We report the synthesis, characterization, spectroscopy, and photochemistry of s-dipentacene (see Figure 1). The symmetric addition product dimer of pentacene (s-dipentacene) is formed upon irradiation of a solution of pentacene. The structure of s-d

The photophysical properties of discrete, catalytically relevant, oxovanadium (VO) sites dispersed in a transparent silica xerogel matrix have been measured by time-resolved techniques. The lowest excited state of this chromophore is a long-lived,

We report the results of resonantly enhanced, degenerate four-wave mixing (DFWM) measurements of the cubic molecular hyperpolarizability coefficient (γ) of four squaraine dyes. Different determinations of γ were performed at 696 and 710 nm with bot

The electronic structure of psuedotetrahedral oxovanadium groups (-O3V=O) dispersed in a silica xerogel matrix, is determined on the basis of a spectroscopic investigation. From this investigation it was found that the highest occupied molecular orbi

Effects due to variation in the alkyl chain length of photodimers of 9-alkylanthracene esters on their photodecomposition efficiencies at 12 K and, by implication, the photoproduct migration as a function of temperature within polymer hosts are inves
