Herein, a novel ESIPT\u2010active salicylaldimine derivative TSP was facilely synthesized through a condensation reaction between salicylaldehyde derivative and 3\u2010phenylpropan\u20101\u2010amine under mild conditions, and fully characterized. X\u2010ray crystallography indicates that intramolecular O\u2013H\u22efN hydrogen bonds endow TSP with favorable ESIPT behavior. TSP exhibits remarkable crystallinity\u2010dependent photochromism: highly crystalline \u03b2\u2010TSP undergoes rapid green\u2010to\u2010yellow fluorescence conversion under UV irradiation within 30\u2009s, while \u03b1\u2010TSP with low crystallinity shows no obvious response under the same conditions. Theoretical calculations and molecular packing analyses reveal that the loose molecular packing facilitates efficient photoisomerization in \u03b2\u2010TSP. Furthermore, TSP\u2010based magnetic powder was developed for high\u2010resolution latent fingerprint imaging, enabling clear visualization of level 1\u20133 details of latent fingerprints on various substrates with high contrast and good transferability. This work demonstrates that TSP is a promising crystallinity\u2010dependent photochromic material with great potential in forensic fingerprint detection.<\/jats:p>","DOI":"10.1002\/bio.70518","type":"journal-article","created":{"date-parts":[[2026,5,20]],"date-time":"2026-05-20T13:37:37Z","timestamp":1779284257000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["An
