透過連續及時間解析光譜，我們發現 MEH-PPV 共軛高分子薄膜中分子鍊交互作用和樣品製程條件有關。
其中drop-casting 製作的樣品中含有大量的 aggregate。利用近場顯微，我們發現鏡鍛燒會改變
樣品的型態學性質。我們認為此一型態學上的變化與分子鍊交互作用有密切的關係。

By incorparating CW and time-resolved spectroscopies, we found that the interchain interaction in a
conjugated polymer, MEH-PPV, is dependent on sample preparation conditions. In particular, aggregates
were found to play an important role in annealed films and thick films prepared via drop-casting method.
With near-field scanning optical microscope, we were able to monitor the changes in film morphology upon
annealing.
