Highly adjustable photonic modules were constructed based on the heterostructures crystals of a new series of donor‐acceptor metal–organic framework (D‐A MOF) featuring highly tunable thermally activated delayed fluorescence (TADF). By introducing N‐phenylcarbazole and derivatives as donor guests into the acceptor host NKU‐111, highly tunable through‐space charge transfer based TADF could be achieved through the engineering of heavy atom effect, which result in modulatable emission wavelength (540 to 600 nm) and enhanced quantum yield (up to 30.86 %). Furthermore, by rationally integrating the D‐A MOFs with distinctive emissions, rod‐like heterostructures crystals featuring excitation position dependent tip emissions in wide wavelength range (495 to 598 nm) could be fabricated, which could serve as highly potential photonic modules for photonic circuit applications.
