A novel organic compound 9-(2,4-dinitrophenyloxy)-3,3,8-trimethyl-1,5-dihydro-[1,3]dioxepino[5,6-c]pyridine (DNPAP) has been synthesized and a nonlinear optical (NLO) crystal has been grown by slow evaporation method. Compound was subjected to different characterization analyses in order to find out its suitability for optoelectronic applications. Single crystal and powder X-ray diffraction analyses show that DNPAP crystallizes in the orthorhombic space group Pca21. The range of optical absorption was ascertained by recording UV–Vis spectrum. The second harmonic generation (SHG) test has shown that DNPAP possesses 6.4-times higher NLO efficiency compared to KDP.
一种新型有机化合物 9-(2,4-二硝基苯氧基)-3,3,8-三甲基-1,5-二氢-[1,3]二氧杂环戊并[5,6-c]吡啶（DNPAP）已经被合成，并且通过缓慢蒸发法生长出了非线性光学（NLO）晶体。为了寻找其在光电应用中的适用性，对化合物进行了不同的特征分析。单晶和粉末 X 射线衍射分析表明，DNPAP 结晶在正交空间群 Pca21 中。通过记录紫外-可见光谱确定了光学吸收范围。倍频生成（SHG）测试表明，与 KDP 相比，DNPAP 的 NLO 效率高 6.4 倍。
