一种潜血指纹显现剂、显现棉片及其应用
摘要：
本发明公开了一种潜血指纹显现剂、显现棉片及其应用。通过Sonogashira偶联反应合成侧链氨基由叔丁氧羰基保护的聚苯撑乙炔撑类共轭高分子，经三氟乙酸脱除保护基团，得到氨基化聚苯撑乙炔撑荧光共轭高分子，将其溶解于溶剂中，即为潜血指纹显现剂。以无纺布为基材，经指纹显现剂浸泡，得到潜血指纹显现棉片，将棉片覆盖于负载有潜血指纹的客体上，揭下后即可在415 nm的紫外光下观察到明亮的指纹纹路。本发明提供的潜血指纹显现的技术方案操作简便，显影时间短，显影效果好，适用于不同客体上的潜血指纹显影；尤其是采用显现棉片，便携，可重复使用和工业化生产，适用于不同情况的现场及各种尺寸的客体的潜血指纹显现。
摘要（英）：

The invention discloses an occult blood fingerprint appearing agent, an occult blood fingerprintappearing cotton piece and application oftheoccult blood fingerprint appearing cotton piece. A polyphenylene ethynylene type conjugated polymer with amino on the side chain protected by t-butyloxycarboryl is synthesized through an Sonogashira coupling reaction, theprotecting group is removed through trifluoroacetic acid, and an aminated polyphenylene ethynylene fluorescence conjugated polymer is obtained and is dissolved in a solvent, so that the occult blood fingerprint appearing agent is obtained.A non-woven fabric is adopted as a basematerial and is soaked through the fingerprint appearing agent, so that the occult blood fingerprint appearing cotton piece is obtained; the cotton piece coversan object loaded with an occult blood fingerprint; and after uncovering the cotton piece, bright fingerprint lines can be observed under ultraviolet light of 415nm. According to the technical scheme,the occult blood fingerprint appearing agent provided by the invention is simple and convenient to operate, short in developing time, good in developing effect, and suitable for occult blood fingerprint developing on different objects; and particularly, by adopting the appearing cotton piece, the appearing cotton piece is portable, reusable, capable of realizing industrial production, and suitablefor occult blood fingerprint appearing of objects in various dimensions on sites with different situations.
