  摘要：

  构建了四苯乙烯（TPE）-碳烷杂化物，并研究了碳硼烷取代基对TPE核的聚集诱导发射（AIE）特性的影响。当用-H，-CH 3或苯基改变碳硼烷单元上的2-R-基团时，相应的TPE衍生物在固态下的发光量子产率可以从0.18调节到0.63。发射颜色表现出明显的100 nm偏移（从蓝色到黄色）。

  Synthesis, Light Emission, Explosive Detection, Fluorescent Photopatterning, and Optical Limiting of Disubstituted Polyacetylenes Carrying Tetraphenylethene Luminogens

  摘要：

  Tetraphenylethene-functionalized acetylenes [(C6H5)(2)C=C(C6H5)(C6H4C equivalent to CR), R = C8H17 and C6H5] were synthesized, and their polymerizations were effected by WCl6Ph4Sn at elevated temperatures in toluene under nitrogen, furnishing polymers P1 and P2. The polymers possessed good solubility and degraded at high temperatures of up to similar to 400 degrees C under nitrogen. Both polymers emitted weakly in the solution state. Whereas the emission of P1 was enhanced when aggregated, that of P2 was quenched, demonstrating that the light emission of polyacetylenes could be varied readily by changing their molecular structure. The polymers could serve as fluorescent chemosensors for explosive detection with an amplification effect. UV irradiation of their films in air photo-oxidized and bleached the fluorescence of the exposed parts, generating fluorescent photopatterns. The polymers exhibited optical nonlinearity and could limit laser pulses.

  A novel series of alkyne-containing potassium organotrifluoroborates were prepared in good yields from the corresponding haloaryltrifluoroborates and various alkynes via Sonogashira coupling reaction. Also, the Suzuki−Miyaura cross-coupling reaction of alkynylaryltrifluoroborates with aryl and alkenyl bromides was achieved in the presence of 5 mol % of Pd(TPP)4 and 3.0 equiv of Cs2CO3 in aqueous 1
