The photoresponsive J-aggregation behaviors of a novel azobenzene-substituted zinc phthalocyanine (azo-ZnPc dyad) were studied by UV/vis, fluorescence, and (1)H NMR spectroscopy. Upon illumination with 365 nm UV light, the trans-cis isomerization of azobenzene can efficiently reduce the steric hindrance around the peripheral oxygen atom of azo-ZnPc,(More)

The photocontrollable J-aggregation of a diarylethene-phthalocyanine hybrid (T-ZnPc) and its aggregation-stabilized photochromic behavior were investigated by various techniques. T-ZnPc initially exhibited slight J-aggregation tendency in solvents such as chloroform and toluene through conformational planarization effect, but formed much stronger(More)
Diaryltriazine derivatives, which are structurally related to diarylpyrimidines, are a representative class of HIV-1 reverse transcriptase inhibitors with remarkable antiviral activities against wild-type and several mutant strains of HIV-1. A series of novel diaryltriazines with a picolinonitrile moiety was reported as potent HIV-1 RT inhibitors in the(More)
A novel family of thiophene-decorated phthalocyanines (M-TPcs) was efficiently synthesized, during which the key intermediate of these compounds was purified through a chemical approach. In the optimized geometries of M-TPcs, the peripherally linked thiophene rings are tilted from the Pc core, which oppose aggregation considering the mutual steric(More)
In this paper, we present a scheme for optimal power allocation of MIMO systems with hybrid SM and STBC employing ZF and SIC detectors to minimize average BER. It's shown from analysis and numerical results that the optimal power allocation depends on many different factors such as modulation, diversity order, coding rate and the number of antennas(More)
Crystallographic overlap studies and pharmacophoric analysis indicated that diarylpyrimidine (DAPY)-based HIV-1 NNRTIs showed a similar binding mode and pharmacophoric features as indolylarylsulfones (IASs), another class of potent NNRTIs. Thus, a novel series of DAPY-IAS hybrid derivatives were identified as newer NNRTIs using structure-based molecular(More)
