method for the construction of boron dipyrromethene dyes absorbing and emitting at longer wavelengths. The fluorescence quantumyields Φ of dyes 1–6 are high (0.7 ≤ Φ ≤ 1.0). The experimental results are backed up by quantum chemical calculations of the lowest electronic excitations in 1, 2, 5, 6, and corresponding dyes of related chemical structure but without conformational restriction. The effect of
