چکیده
Abstract Herein, we have studied the exciton dynamics of a novel fused ring π -conjugated molecule (YS3) in solution and film states by spectroscopic measurements. This incorporates dithienonaphthobisthiadiazole as core unit that is two-dimensionally -extended ring. As result, found long lifetime YS3 films originating from reduced radiative nonradiative transitions. partly because deactivation effectively suppressed dipole-forbidden transition H-aggregates rotational crystalline state.

متن کاملTwo-dimensional, phenanthroline-based, extended π-conjugated molecules for single-molecule conduction
The conduction properties of phenanthroline-terminated, polycyclic extended rr -conjugated molecul ar wires are investigated using density fun ctional theory (OFT) in combination with Green 's function techniques and group theory. While these molecules could possibly be thought of as accessible graphene-like fragments, they are calculated to conduct poorly. The decay constant for their exponent...

Software package Mathematica is used for computer simulation of steady state fluorescence spectra of ring molecular system. The cyclic antenna unit LH2 of the bacterial photosystem from purple bacterium Rhodopseudomonas acidophila can be modeled by such system. Dynamic disorder, interaction with a bath, is included in Markovian approximation. Also three different models of uncorrelated static d...
