Abstract Host‐guest conjugate is a promising strategy for providing outstanding molecules. Herein, we designed host‐guest HG1 , which comprises hydrophilic host unit, tetraaza[2.2.1.2.2.1]paracyclophane CPX 2 with microhydrophobic cavity, and guest 2,3‐naphthalimide fused two benzothiophenes G1 exhibiting fluorosolvatochromism, linked an oxyethylene chain. initially showed fluorescence band at 585 nm in MeOH/H O (1/499 v/v); however, this decreased time, instead, new 430 appeared. The CIE chromaticity diagram that the fluorescent color changed from yellow‐orange to blue via white. NMR analysis of methanol‐d 4 exhibited different signals unit between yellow structures. structures asymmetrical assigned as affected by cavity environment unit. Consequently, can form conformations: In‐form Out‐form. In In‐form, inside hydrophobic shows fluorescence. Out‐form, outside aqueous solvent. Therefore, performs ratiometric fluorophore depending on in/out isomerism conjugate.

Abstract Blue phase liquid crystal (BPLC) dynamic patterns have attracted wide attention for promising applications in optical information manipulation and visualization sensing, owing to unique 3D chiral helix superstructure adjustable bright/abundant colors response extra fields. Inkjet printing has become an efficient approach achieving programmable BPLC patterns. However, it remains a challenge achieve independent “on/off” control of regional using the same ink due unrevealed temperature‐time‐dependent color change behavior determined by different inks. Herein, comprehensive understanding reflective bandgap shift law versus temperature/time is established investigating diffusion kinetics multiple inks (5CB, 6CB, 8CB) hydrophobically modified blue‐phase polymer templates. The three induce redshift followed blueshift color/reflectance wavelengths, but triggering times differ significantly at temperature, which attributed inks' transition characteristics, fluid properties, interaction with network. Dynamic multi‐color selective region are successfully fabricated based on time‐temperature controlled multi‐ink technique displaying time‐series multi‐level encryption (including “growing apple tree” “nested QR codes”). This study provides important insights into design fabrication advanced devices

Abstract Circularly polarized luminescence (CPL) material has been widely exploited in 3D display, information encryption, etc. However, situ generation and dynamic modulation of CPL signals to achieve programmable patterns remains challenging due elusory interactions between fluorescence the chiral microstructures. A novel strategy is proposed combining controllable magnetic field‐assisted assembly photo‐patterning technique form twisted stacking heterostructure, consisting orientated Ag@Fe 3 O 4 nanowires (NWs) polydimethylsiloxane (PDMS) film embedded with achiral dyes polydiacetylene (PDA) chains. In a designed system, PDA chains after photo‐polymerization can serve as polarizer produce linear fluorescence, while aligned NWs on surface PDMS films act phase retarder, favoring generation. Furthermore, characteristics, including wavelength handedness, be switched by thermo‐chromatic transition PDA, thus, micropatterns tailorable distributions achieved. By employing above two orthogonal channels, system possesses brilliant storage capabilities, multistage encryption. This study proposes for fabrication toward multiple
