“…Triazene derivatives are considered as polyazoic compounds containing a diazoamino moiety (-N=N-N˂) with three consecutive nitrogen atoms in an acyclic form [1][2][3]. These compounds are used in medicine [4,5], in organic synthesis as protecting groups [6][7][8], in the preparation of semiconductors and nano-electronic materials [9], in metals [10,11] and proteins [12] detection as colored and fluorescent ligands, and in the heterocyclic compounds synthesis [13][14][15][16]. However, to the best of our knowledge, few dyes based triazene derivatives have been reported in the literature [17,18].…”
