Photophysical studies of neutral aromatic species confined in zeolite L: Comparison with cationic dyes
TL;DR: In this article, the photophysics of a few aromatic molecules incorporated into the straight channels of zeolite L were investigated, mainly by luminescence spectroscopy, and it was found that the dimer formed in NaKL has less overlap than that formed in KL.

Intramolecular Excimer Formation in Short- and Long-chainlength di(9-anthryl) Bichromophoric Compounds and Relation to Ground State Properties
Wolfgang Rettig,Barbara Paeplow,Heinz Herbst,Klaus Müllen,Jean-Pierre Desvergne,Henri Bouas-Laurent +5 more
TL;DR: The ground state conformational, UV absorption and fluorescence spectral as well as decay time data for a series of polymethylene- and one polyoxyethylene-linked di(9-anthracenes) in solution are compared, for chainlengths varying from n=0 (directly linked system A0A, 9,9′-bianthryl) to n=∞ (A∞, reference system 9-decylanthracene). 1H NMR spectroscopy of A2A to A11A shows that there is no clearly preferred

Intramolecular excimer formation of oligostyrenes from dimer to tridecamer: The measurements of rate constants for excimer formation, singlet energy migration, and relaxation of internal rotation
TL;DR: In this paper, the emission properties of styrene oligomers from dimer to tridecamer were investigated by picosecond pulse radiolysis at room temperature, and it was shown that there is a discrepancy between the results of photostationary measurements with those of transient methods.

Kinetic study of photophysical and photochemical processes in α,ω-(bis-9-anthryl)-n-alkanes (ethane to decane) at room temperature
TL;DR: Fluorescence and photocyclomerization quantum-yield measurements and a transient kinetic analysis were performed for a series of α,ω-(bis-9-anthryl)- n -alkanes (A-C 2 -A to A-C 10 -A and A-mXy-A) in methylcyclohexane and ethanol as mentioned in this paper.

Normal and second intramolecular excimer fluorescence of 1,3-bis(4-methoxy-1-naphthyl)propane and 1,3-bis-(4-hydroxy-1-naphthyl)propane
TL;DR: In this paper, the authors show that 1,3-bis(4-methoxy-1-naphthyl)propane and 1, 3-bis (4-hydroxy-1 naphthsyl)-propane (BHNP) give fluorescence spectra showing the existence of two types of excimer: one with a peak at ≈ 410 nm (normal excimer) and the other at ∼ 370 nm (second excimer), the fluorescence from the second excimer increases with decreasing temperature of the solution, but disappears in the

Absorption and Excimer Fluorescence Spectra of Sandwich Dimers of Substituted Anthracenes
TL;DR: In this article, the absorption and fluorescence spectra of substituted anthracenes are reported and the resonance splittings are about 400 cm−1 for the 1A1g→1B2u transition (of anthracene) and about 1500 cm− 1 for 1A 1g→ 1B3u transition.
