4,4',4'',4'''-(pyrene-1,3,6,8-tetrayl)tetraaniline

4,4',4'',4'''-(Pyrene-1,3,6,8-tetrayl)tetraaniline is a tecton fluorescent probe linker with four aniline side arms extending the pyrene core at 1,3,6,8-positions. Two new conjugated pyrene-based covalent organic frameworks (COFs), namely PyDF-COF and PyBMT-COF, could be prepared through condensation polymerization of 4,4',4'',4'''-(pyrene-1,3,6,8-tetrayl)tetraaniline and 2,5-difluoroterephthalaldehyde or 2,5-bis(methylthio)terephthalaldehyde, respectively[1].
