<P><B>Abstract</B></P> <P>A reversible red-yellow color change in PDA (polydiacetylene) was achieved by controlling the head group of the diacetylene molecules. Typical PDAs show blue-red color transitions, and this reversible red-yellow color transition could be applied to various sensing applications. The introduction of an alkyl substituent to the head group as an internal stimulus resulted in a primary blue-red color change, and this change became clearer as the length of the alkyl chain became longer. The PDA vesicle, once colored red in response to an internal stimulus, showed a reversible and very selective red-yellow color change in response to a second external stimulus, such as temperature or pH.</P> <P><B>Highlights</B></P> <P> <UL> <LI> A reversible red-yellow color transition of PDAs was achieved by alkyl chain induced PCDA-Oct. </LI> <LI> Stepwise blue-red-yellow color changes are suggested through internal and external stimuli. </LI> <LI> Both temperature and pH sensing were successfully performed using modified PCDA-Oct. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
