含氟化合物分子之間具有氟-氟、氟-氫的交互作用，引入長氟鏈可影響分子間之堆疊。由於化合物能引入基團的位置有限，引入分枝氟鏈可提升化合物含氟比例，並避免使用長氟鏈而導致之生物累積性。本論文改良文獻中合成分枝氟鏈之方法，並開發出新的分枝氟鏈、引入不同官能基（如胺基、重氮、乙烯基）。本論文將氟鏈引入發光團（苝雙醯亞胺、α-氰基二苯乙烯），探討分枝氟鏈對於溶液態、聚集態與固態之光物理性質之影響。在苝雙醯亞胺的苯環區與醯亞胺皆成功引入分枝氟鏈，含分枝氟鏈苝雙醯亞胺於溶液態的螢光量子產率高，而於聚集態有分子聚集螢光淬滅，但也觀察到激發雙體的形成。於α-氰基二苯乙烯醯胺鍵的間位引入分枝氟鏈醯胺，其溶液態螢光量子產率低，但聚集態有聚集誘導發光的現象；在靠近氰基的苯環引入分枝氟鏈的α-氰基二苯乙烯，其溶劑中螢光量子產率高但聚集時螢光下降。
