Photophysical properties and structural analysis of modified methylene blues as near infrared dyes

[Display omitted] •The UV–vis absorption spectra for MBI, MBPF6, and MBBPh4 are identical to the original MB and exhibit peaks at 655nm.•The solubility in the media could be controlled by the counter anion without change of absorption spectrum.•3,7-Bis(diphenylamino)phenothiazinium chloride 3 (MB 3)...
