中文摘要：
我们发现了醛基二芳烯BMFTP的溶剂变色效应：1）在醇类溶剂中，醛基二芳烯分子闭环态吸收波长将会发生显著红移；2）在不同溶剂中，醛基二芳烯闭环态吸收波长不同。固态二芳烯分子在饱和了溶剂的蒸汽中也有类似现象。我们提出了可能的机理和解释并为此进行了初步的验证。由此提出无损读出方案：用醛基二芳烯在两种不同溶剂中形成不同颜色的溶液，分别用以表示0和1。适当组合这种溶液以记录数字化信息。在读出的过程中，醛基二芳烯向开环态变化，信息慢慢地隐藏。当用紫外光重新发色后，信息又可准确无误地显示出来：在读出的过程中，信息保持完好，实现无损读出。
英文摘要：
An unprecedented combination of photochromism and solvatochromism for a 1, 2-bis （dithienyl） cyclopentene derivative, 1,2-bis （2-methyl-5-formyl-thien-3-yl） perfluorocyclopentene （BMFTP）,is observed：1 ） BMFTP, dissolved in the alcohols, exhibits the largest positive solvatochromic shift in wavelength witnessed to date. 2）the characteristical absorbance wavelengths of BMFTP vary in different solvent. Solid BMFTP in air saturated with solvent vapor also exhibits similar phenomenon. Based on these, a non-destructive solution of readout is suggested： different BMFTP solutions in two solvents could represent 1 and 0, whose combination would store information. When readout, BMFTP would transfer into close-ring state, which is colorless; and when lighted with appropriate violetlight, BMFTP recover into open-ring state and the solutions return to original state. As a result, the information keeps perfect and non-destructive readout is achieved.
