第一章：我們發展了經由鋅金屬或鈧金屬催化劑可以使各種不同的炔醯胺和亞硝基苯在室溫下進行類納扎羅夫環化反應，得到吡咯架構產物，另外我們也嘗試不同取代位置的甲基亞硝基苯，均得到良好的產率，可作為天然物的前驅物。 第二章：我們利用酸活化的方式將不同的炔醯胺和多種苯腈反應，得到七種以嘧啶為核心結構的發光材料，並對他們進行基本的光學性質的量測。產物的吸收波長最大範圍在258 ~ 332 nm 之間，多為紫外光區，最大放光波長範圍在 336 ~ 457 nm 之間，最高螢光量子效率為79%。將來可藉由結構上的調整，進一步應用在紫外光有機發光元件上。
Chapter 1 : The first chapter describes the zinc-catalyzed or tin-catalyzed reaction with diverse ynamides and nitrosoarenes through aza-Nazarov cyclization, allowing the facile and efficient synthesis of various 2-aminopyrroles in moderate to good yields. This pyrrole fragment can be the precursor of several nature molecules.
Chapter 2 : The second chapter describes concise TfOH-mediated [2 + 2 + 2] cycloaddition of ynamides with two discrete nitriles to synthesize seven pyrimidine-based emitters following by measurements of optical properties. These new derivatives show near-UV and blue fluorescent emissions (336 ~ 457 nm) with moderate quantum yields. One emitter (II-4g) was given an outstanding PL quantum yields (ηPL = 79%) with NUV emission which can be adjust and apply in UV-light OLED devices.

[5] Despite being potentially misleading, the author does not refrain from using terms such oxa-Nazarov, homo-Nazarov, etc. The reader is once again reminded of the “formal” connection to the original cyclization.
