Abstract Two dumbbell‐shaped building blocks (TMB and TMBT), featuring methyl benzoate groups as hydrogen bond units, are selected to construct heterostructures of HOFs, aiming achieve multiple functions including white luminescence, stimulus‐response behavior, well application in information encryption. TMB molecules self‐assembled form a flexible HOF (X‐HOF‐8) p‐xylene, containing solvent channels blue fluorescence. Upon removal guests, it can transform into nonporous crystal with gray In contrast, TMBT forms guest‐free (X‐HOF‐9) displaying orange They could bulk heterojunction (BHJ) HOFs energy transfer from TMBT, exhibiting composition‐dependent fluorescent color. Notably, emission be achieved BHJ converted fluorescence upon guest removal; subsequently, is restored re‐capturing guests. Furthermore, rod‐like triblock (THJ) also constructed, which exhibit regulatory behavior response gaining or losing The unique luminescent characteristics stimulus responsiveness these make them an excellent platform for applications anticounterfeit. This represents the pioneering achievement light HOF, groundbreaking realization THJ remarkable exciting characteristics.

Photochromic hydrogen-bonded organic frameworks (HOFs) can introduce different luminescent functional groups to achieve synergistic controlled multiple color change properties, which are in great demand for diverse information encryption applications. We report this paper switchable photochromic and photoluminescent dual group HOFs constructed with effects by N,N′-bis(2-phenylalanine)-1,4,5,8-naphthalenediimine (H2PheNDI) benzenecarboximidamide 4,4′-azobis(hydrochloride) (AZBH). The crystal powder of iHOF-41 is orange–red color, be changed black under the irradiation a 365 nm ultraviolet (UV) light source 15 min. photoisomerization rate solution continuous UV 5 h was close 99%. composite membranes properties photochromism photoluminescence when they discolored and, at same time, excite red bright fluorescence. This work achieves construction based on switching biluminescent explores mechanism process as well its practical application encryption.
