With sensors 1 and 2 we were interested in demonstrating some degree of analogy with the PRC from a functional, rather than structural, viewpoint. We used two regioisomeric sensors, each of which has only one PET pathway, such that the arguments for self‐regulation could be developed with maximum clarity. Two PET pathways are possible for one sensor molecule when two distinguishable dialkylaminoethyl groups are attached to the imide nitrogen and the 4‐amino group of the 1,8‐naphthalimide nucleus. Then the analogy with the PRC becomes apparent even in structural terms. While sensors 1 and 2 do not display symmetry breaking during PET, we note that symmetry breaking within the PRC assumes that the effects of the protein matrix and the carotenoid can be neglected. See refs. [1c,3]. We thank the referees for initiating these comments.

(a) The sensors were prepared in two stages. The derivatization of 4‐chloronaphthalic anhydride with an amine to yield the corresponding 4‐chloronaphthalimide is much faster than the subsequent nucleophilic aromatic substitution of the 4‐chloro group by an amino moiety. Proper choice of N,N‐dialkyl‐N‐(2‐aminoethyl)amine or 1‐butylamine as the reactant in the second step allows the synthesis of 1 and 2. Synthetic procedures were adapted from, J. Chem. Soc.

Protons were studied in the first instance. Other guests can be studied by changing the receptor since the fluorescent PET sensor principle is quite general [5].

When the thermodynamic driving force for PET is calculated by the usual Weller‐type thermodynamic cycle with redox potentials, ion pairing energy, and singlet energy [9], there is no opportunity to allow for the effect of the photogenerated internal electric field. This appears to be due to the fact that the internal field is only generated after photon absorption. Thus the effect of the internal field can be viewed as being largely kinetic. We are grateful to a referee for catalyzing this discussion.
