Through-bond coupling across a cyclodiborazane core results in large absorption cross sections in a new type of boron-containing two-photon-absorbing chromophore (see picture; B pink, N blue, C gray, H other than BH (white) omitted). This is a first step in the design of new dual-property chromophores for applications in biological science or medicine (e.g., two-photon imaging and boron neutron capture therapy).
