The thermally activated internal conversion (IC) taking place in 4-substituted 1-(dimethylamino)naphthalenes (14DMX) and 1-aminonaphthalenes (14ANX) with X=CN, Cl, H, CH3 and OCH3 was investigated in three solvents spanning the polarity scale, hexane

With the 1-aminonaphthalenes 1N5 and 1DMAN a fast radiationless process occurs in n-hexane, diethyl ether, and acetonitrile, which is shown to be internal conversion (IC). The IC reaction is slower with 1N4 and much less efficient with 1MAN and 1AN.

To address the issue of electronic interaction between donor (D) and acceptor (A) moieties in intramolecular charge transfer reactions a series of chemically closely related extended π-systems has been investigated. These compounds contain pyrene an

Magnetic field effects (MFE) detected by intramolecular exciplex fluorescence have been studied in acetonitrile solutions for new donor−acceptor compounds in which pyrene is linked to aza-15-crown ether by a polymethylene chain with 3, 9, and 16 CH

A discussion is presented of the fast excited state intramolecular charge transfer (ICT) and dual fluorescence observed with several 4-aminobenzonitriles. The occurrence or absence of this ICT reaction is shown to be determined by the magnitude of th

The fluorescence decays of trans-4-dimethylamino-4′-cyanostilbene (DCS) and trans-4-azetidinyl-4′-cyanostilbene (ACS) in an unpolar (n-heptane) and a polar (acetonitrile) solvent are single exponential down to a time resolution of around 5 ps and

The influence of external magnetic fields on the spin dynamics and recombination reaction yield of radical ion pairs, generated by photoinduced electron transfer between pyrenyl and dimethylaniline linked by an oligopeptide bridge, was studied. From

Time-resolved transient absorption (TRABS) experiments were carried out on a picosecond to nanosecond time scale in order to determine the mechanism of photoinduced hydrogen transfer between benzophenone (Bp) and dimethylaniline (DMA) covalently link

Dual fluorescence and intramolecular charge transfer (ICT) are observed with aminobenzonitriles when two excited state levels (S 1 and S 2 (CT) in DMABN) have an energy gap sufficiently small for vibronic coupling: a solvent-induced pseudo-Jahn-Telle
