基于N→B配位鍵構(gòu)筑的結(jié)晶加合物的合成及性能研究摘要：本文以N→B配位鍵構(gòu)筑為基礎(chǔ)，探究了一系列新型結(jié)晶加合物的合成及性能研究。通過配位鍵構(gòu)筑，在加合物中成功引入了醇類、酮類、酸類等活性官能團，并利用X射線衍射、化學(xué)分析等手段對加合物的結(jié)構(gòu)和組成進行了表征。實驗結(jié)果表明，N→B配位鍵構(gòu)筑的加合物具有良好的熱穩(wěn)定性和化學(xué)穩(wěn)定性，并能在不同環(huán)境下發(fā)揮出一定的性能。此外，本文還對加合物的光致發(fā)光、電化學(xué)性能等進行了研究，結(jié)果表明，這些加合物具有一定的光學(xué)、電學(xué)性能，可廣泛應(yīng)用于光催化、傳感、生物醫(yī)學(xué)等領(lǐng)域。
