A series of pure organic halogenated hexaphenylmelamine (HPM) derivatives featuring remarkably weakened ultralong room-temperature phosphorescence (RTP) were meticulously investigated. As the p-substituted atoms of these HPM derivatives sequentially changed from H to F, Cl and Br, both the RTP lifetimes and efficiencies dramatically decreased from 608 ms with 13.4% (HPM-H) to 337 ms with 5.3% (HPM-F), 99 ms with 1.3% (HPM-Cl), and 2.8 ms with undetectable efficiency (HPM-Br), respectively. Most notably, the severely weakened efficiencies are fundamentally different from the trends of the effect of halogenation on phosphorescence properties previously reported. Coupled with experimental results and theoretical simulations, the subtle change of molecular packing induced by halogenation should be responsible for the distinctive RTP properties. This finding not only provides a unique halogen-involved RTP phenomenon, but also offers a very special perspective to understand the effect of halogenation on phosphorescence.

A series of bistriazine-based streptocyanines has been selectively prepared. A variety of substituents has been introduced into the triazine ring with p-phenylenediamine as a conjugated spacer between the triazine and the streptocyanine moieties. Fukui in

Triamino-s-triazine triradical trications. An experimental study of triazine as a magnetic coupling unit

, p. 171 - 174 (2007/10/03)
(equation presented) Triamino-s-triazine derivatives 3a, 4, and 5 have been prepared, and their cationic states have been analyzed electrochemically. At 298 K, 3a+ has a limited lifetime in CH2CI2 solution. However, 4+ and 5+ are long-lived under such conditions, and quartet states of 43+ and 53+ are observed by ESR spectroscopy. Variable-temperature ESR analysis and NMR shift susceptibility measurements indicate that 53+ is a doublet ground state with a populated quartet state.
