Triphenylamine (TPA) and N-methylbarbituric acid/indanedione-based donor–acceptor derivatives were synthesized and demonstrated molecular conformation and packing dependent tunable fluorescence from yellow to red in the solid state. TPA with N-methylbarbituric acid (BA-1) showed bright yellow fluorescence (λmax = 550 nm, Φf = 22.8%) whereas OCH3 substitution at the phenyl rings of TPA, (BA-2 and BA-3) produced strong red (λmax = 602 nm, Φf = 41.1%) and orange fluorescent solids (λmax = 582 nm… Expand
