Two novel quadrupolar organic compounds, 3-(4-((E)-2-(9-butyl-9H-carbazol-6-yl) vinyl)styryl)-9-propyl-9H-carbazole (BCSPC) and 3-(3-(3-((1E)-2-(4-((E)-2-(3-(3,5-bis(9-butyl-9H-carbazol-6-yl)phenyl)-9-butyl-9H-carbazol-6-yl)vinyl)phenyl) vinyl)-9-butyl-9H-carbazol-6-yl)-5-(9-butyl-9H-carbazol-6-yl)phenyl)-9-butyl-9H-carbazole (BCPBC), with different conjugated arms, have been designed and synthesized. Their one-and two-photon absorption (TPA) and excited fluorescence properties have been experimentally investigated. The two-photon absorption cross-sections of two compounds were estimated by two-photon excited fluorescence technique using 200 fs, 76 MHz, Ti:sapphire laser, which are 22 and 154 GM for BCSPC and BCPBC, respectively. The optimal excitation wavelengths are 780 nm for both BCSPC and BCPBC. A data recording experiment proved the potential application of the materials.

编者按:之前作者关于“房地产税基争议处理”的系列文章刊发后,引起业界读者的广泛关注。作者在长期的课题研究与国际交流过程中,积累了丰富的国际上关于房地产税(财产税)争议处理的案例,这些案例对于即将开征房地产税的中国来说无疑具有非常重要的借鉴作用。今后我刊将继续邀请作者精选翻译、分析和整理出一些具有代表性的案例,以期为业界理论研究与实践带来启发。  美国财产税的征收目的,最初是满足独立战争的需要,后来
