To meet the need of intelligent systems, the development of photoresponsive ultralong RTP materials is highly desirable, however it remains a challenge due to the lack of rational design strategies that can leverage RTP and photochromism effectively. Herein, we report a new type of onedimensional (1D) metal-organic halides (MOHs) that simultaneously exhibited dynamic ultralong RTP and photochromic optical waveguide with a large switching ratio, obvious visualization contrast, and robust reversibility. These properties facilitate future applications for multi-color photonic barcodes and optical logic gates. Moreover, benefiting from the color-time-space multi-dimensional tunable ultralong RTP, this 1D microrod displayed a multi-mode luminescent signal output, with significantly higher information storage capacity than typical fluorescent systems. Therefore, this work demonstrates a new 1D color-tunable optical waveguide and photo-responsive ultralong RTP based on molecular self-assembly of MOHs, and extends frontier photonic applications as multi-level data encryption and information storage at the micro/nanoscale.
