alkyl, and A represents an ethylene group, a 1,2-propylene group, a 1,2-butylene group or mixtures of ethylene oxide groups and 1,2-propylene groups or mixtures of ethylene oxide groups and 1,2-butylene groups, and m is a number from 2 to 30, are suitable for improving the action of agrochemical active substances in and on plants.
A process for the preparation of linear alpha olefins having 2n carbon atoms from linear alpha olefins having n carbon atoms comprising the steps of (a) dimerizing a linear alpha olefin having n carbon atoms in the presence of a dimerization catalyst to produce a linear internal olefin having 2n carbon atoms; (b)(i) reacting the linear internal olefin having 2n carbon atoms produced in step (a) with a trialkylaluminium compound in the presence of a catalytic amount of an isomerization/displacement catalyst in order to cause isomerization of the linear internal olefin and to displace alkyl group(s) from said trialkylaluminium compound to form an alkyl aluminium compound wherein at least one of the alkyl groups bound to aluminium is a linear alkyl which has been derived from the isomerization of said linear internal olefin; and (b)(ii) reacting said alkyl aluminium compound with an alpha olefin optionally in the presence of a displacement catalyst so as to displace said linear alkyl from said alkyl aluminium compound to form a linear alpha olefin having 2n carbon atoms.
A rylene-based polychromophore of the general formula I
in which the variables are each defined as follows:
rylene is a radical of the formula
which has been functionalized by at least one imide group, ester group or amide group and which may additionally be substituted by aryloxy, arylthio, hetaryloxy and/or hetarylthio;
X is a rylenedicarboximide radical which absorbs at a different wavelength from the rylene radical, is bonded to the X radical in the peri-position via Y via a moiety
—Y′-A-Y—,
is bonded to the rylene radical and may likewise be substituted by aryloxy, arylthio, hetaryloxy and/or hetarylthio;
A is a bridging member having at least one aromatic or heteroaromatic radical, the Y or Y and Y′ groups being bonded to the aromatic or heteroaromatic radical;
Y is a moiety
Y′ is a moiety
where the moieties (i) and (ii) may be part of the ester groups of the rylene radical and the moieties (iii) are part of the imide groups of the rylene radical and the moieties (iv) are part of the amide groups of the rylene radical;
