Catalyst-free single-molecule cascade photoreactions for spatiotemporally programmed encryption.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The escalating crisis of information leakage necessitates a shift from static identifiers to intelligent, dynamically secure systems. Current approaches, even up-to-date time-dependent ones, remain constrained by non-progressive or multicomponent designs that lack programmable spatiotemporal control, underscoring the need for a minimal, integrated molecular platform. Herein, we report a single-molecule system (4BT-Py-PTC) that achieves time-gated, graded multicolor fluorescence via sequential, catalyst-free photoreactions. This designed pathway involves thiocarbonate hydrolysis, alkene cleavage, and aldehyde photooxidation, progressively transforming the initial yellow emitter into red- (3BT-Py, 5 min), yellow- (2BT-CHO, 20 min), and blue-emissive (5BT-COOH, 80 min) products. This intrinsic programmability enables a higher-order of spatiotemporal command. Leveraging this output, we demonstrate two encryption modes: time-gated 3D codes and organogel matrices for multistage (reveal-conceal-erase) control with temporal keys. This work establishes an approach centered on catalyst-free, single-molecule cascade photoreactions, redefining secure materials through spatiotemporal encryption and benchmarking dynamic anti-counterfeiting and data protection.
