(λPL: 483 nm; FPL: 59%; ΔEST: 0.09 eV; neat film), with the excited-state behavior being modulated as a result of the interactions between the two adjacent donor dendrons. The paraconnection of the donor dendrons in tBuCz2m2pTRZ leads to strong electronic coupling between donor and acceptor, as evidenced by the strong molar absorption for the ICT transition, whilst the additional meta-connection in tBuCz2m2pTRZ results in a small DEST as the metadisposed donor and acceptor groups are electronically decoupled. The λPL of tBuCz2pTRZ is similar to that of tBuCz2mTRZ, indicating similar energies of their 1 CT states regardless of the electronic coupling between donor and acceptor. The spectral red-shift of tBuCz2m2pTRZ
