Schematic structure of the DCDHF fluorophores. The amine donor and DCDHF acceptor are connected by a π-conjugated linker. The R1–R4 groups can be modified (usually without affecting the photophysics) in order to add reactive functionality or increased solubility. The naming scheme used in this paper specifies the π system: “DCDHF-(π unit closest to acceptor)-...-(π unit closest to donor)” with the π units denoted P = phenylene, V = vinyl, T = thiophene, N = naphthalene, A = anthracene; the amine donor is not specified because it is present in all structures (see Table 1 for structure drawings.)
